CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 545,427, dated August27, 1895.

application filed June 15, 1895- Serial No. 552,947. (No model.)

To all whom it may concern.-

Be it known that I, FRANK HENSLEIN, J r., a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Gar-Brakes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to improvements in car-brakes, the same beingespecially applicable to use upon electric and cable cars and also uponrailway-cars where it is important to stop the movement of the carsuddenly.

The invention consists of a car having the usual front and rearplatforms, trucks, wheels, 850., a transverse frame secured to the underside of the car, preferably at the center, in which frame is mounted insuitable bearings a beveled gear-wheel having arms extending outwardlytherefrom, which are connected through suitable rods and chains with thebreak operating shaft projecting upward through the front and rearplatforms of the car. The beveled cogwheel referred to meshes with twobeveled pinions mounted upon the ends of a pair of horizontal shaftsmoving in suitable bearings and having secured to them the lower ends ofa pair of chains, which are connected at their upper ends to a block inwhich are pivoted two arms, which are also pivoted to levers, upon thelower ends of which a pair of brake-shoes are secured.

The invention also consists in other details of construction andcombinations of parts, which will be hereinafter more fully describedand claimed.

In the drawings, Figure 1 represents a side elevation of a car-body,showing the usual trucks with my brake mechanism secured thereto. Fig. 2is a bottom plan view of the same. Fig. 3 is a plan view with the bottomwith the car-body removed. Fig. 4 is a section on the line to w of Fig.3. Fig. 5 is a section on the line y 'y of Fig. 3.

Like reference-numerals indicate like parts in the various views.

My brake mechanism is adapted to be attached to railway-cars of theusual form of construction.-

In the drawings, 1 represents a car-body having the front and rearplatforms 2, frame 3, and wheels 4 4:. Connecting each pair of trucks onopposite sides of the car are longitudinal beams 5 5,which serve tosupport the frame 6, in which my brake mechanism is mounted. The frame 6is made up of two castings 7 7, suitably secured together, and in thelower part of said frame is rotatably mounted a beveled cog-wheel 8,having diametricallyarranged arms 9 9 extending outwardly therefrom.Connected to the outer ends of the arms 9 are rods or pitmen l0 10,connected at their outer ends through chains 11 11 to the lower ends ofthe brake-operating shafts 12 12, of the usual form of construction. Thebeveled cog-wheel 8 meshes with apair of beveled pinions 13 13 upon theends of short shafts of drums 14 14, which move in suitable bearings inthe frame 6. These shafts or drums have connected to them chains orcords 15 15, which are in turn connected at their upper ends to a block16, moving in guides between the two castings 7 of which the frame (3 ismade up; Pivoted to the upper end of the block 16 and extendingdownwardly and out,- wardly therefrom is a pair of rods 17 17, in turnpivoted to levers 18 18, fulcru med at their inner ends to a block 19between the two castings 7, extending downwardly at their outer ends andhaving secured to them in any suitable manner the brake-shoes 20 20,which are adapted to engage the rails upon which the car moves. Betweenthe stationary block 19 and the movable block 16 I place a pair ofcoiled springs 21 21, through the action of which the brake-shoes 20 arekept normally out of engagement with the rails.

My brake may be operated from either end of the car by turning theoperating-shaft 12, which withdraws the rods or pitmen 10 through thechains 11 and turns the beveled gear-wheel 8 in its bearings. Thegear-wheel 8 in turn rotates the shafts or drums 14 through the pinions13 and winds the chains 15 upon them. This withdraws or forces downwardthe movable block 16, which, acting through the rods 17 and levers 1S,throws the brakeshoes 20 down in contact with the rail and brakes thecar.

By the use of my invention I am enabled to brake the car quickly andconveniently and stop it almost instantaneously. Furthermore, by using atrack-brake instead of one which engages the rim of the wheel the wheelsthemselves are not ground down fiat, causing slipping on the rails.

new ones inserted thereon in a convenient manner, or they may bereversed, if desired. Having now described my invention, what I claim asnew, and desire to secure by Letters Patent, is-- 1. In a carbrake, thecombination of a frame adapted to be secured to the under side of;

the car, a cog wheel rotatably mounted in said frame, brake operatingshafts on the front and rear platforms of the car, connections between Isaid shaft and said cog wheel, a pair of shafts having pinions attheirouter ends, which mesh with said cog wheel, brake shoes and connectionsbetween said brake shoes and said drums, whereby upon. operating theshafts upon the platform of the car, said brakes may be thrown down incontact with the rails, substantially as described.

2. In acar brake, the combination of a frame adapted to be secured tothe under side of the car, a cog wheel rotably mounted in said frame, apair of diametrically arranged arms projecting outwardly from said cogwheel, pitmen connected to the outer ends of said arms, brake operatingshafts mounted on the front and rear platforms of the car, a flexibleconnection between said shafts and said pitmen,

j a pair of horizontally arranged shafts or The brake-shoes 20 may beremoved and drums having pinions on their outer ends meshing with saidcog wheel, a block moving in Ways in said frame, chains connecting saidmovable block and said shafts or drums, a pair of levers pivoted to astationary block in said frame having brake shoes secured to theirouteren'ds, rods connecting said movable block and said lever, andsprings between said stationary and movable blocks, substantially as andfor the purpose described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
